Dorman 712-645M4 Wheel Lug Nut

Dorman 712-645M4 Wheel Lug Nut Overview

Dorman 712-645M4 is a metric wheel lug nut built from medium carbon steel with a Hyper Silver finish and a 60-degree conical seat. It is designed for vehicles that use an M14 x 1.50 fine thread and a 19 mm hex, with a right-hand thread direction for standard wheel service.

For drivers servicing Chevrolet Silverado, GMC Sierra, or Dodge Charger wheel hardware, this lug nut offers a clean chrome-style appearance with corrosion resistance and scratch resilience. The Dorman 712-645M4 also supports a custom racing-style look while maintaining the fit and thread specifications needed for proper wheel retention.

Detailed Description

This wheel lug nut is engineered for a wide range of GM, Ford, Toyota, Lexus, Dodge, Honda, and other applications that use the specified thread and seat style. It is a direct-fit style wheel lug nut for many vehicles including Chevrolet Silverado 1500, GMC Sierra 1500, and Toyota Tundra, where the wheel-to-lug interface must match the conical seat and M14-1.50 thread pattern. The Dorman 712-645M4 is also listed for select Cadillac, Buick, and Chrysler models, making it a practical replacement for common OE-style wheel hardware service.

This part cross-references OE-style wheel lug nut applications for the same fitment family.
